I really liked the idea of doing the same thing but using them inboard, for example close to where the diff would be. It all looked good but the rpms when used with the Kelly controller, if I remember correctly where about 1500 so if you do your maths, it did not make for a great top speed.

The motor is designed for motorcycles as stated on the web site and is 10KW continous not 30 KW
Also the motor is 90 plus eff at 75% of max speed. Huge amount of work was done to minimize eddy currents at speed to improve eff. This is a custom design that cost EnerTrac a huge amount of money to develop.

EnerTrac Corp. has several test motorcycles all are welcome to test ride and judge the performance and range for oneself.
We are located in Farmingdale, NY

EnerTrac and EV propulsion are working on a electric differential version of the motor for small cars. We'll have something to show in a few weeks.

Anyway please don't bad mouth a product for a application its not intended for. When we come out with the car version it will be with a working car, then you can judge if the product meets your needs. We are also working on a controller to match to the motor for a greatly reduced cost compared with what is now available

Really? I thought 1500rpm with a 25" tire was over 100mph? How much faster do you need to go?
